COMBINED CORK AND SCREW NOZZLE.

SPECIFICATION forming part of Letters Patent No. 287,046, dated October23, 1883.

Application filed August 2,1883. (No model.)

T LLZZ whom it may concern.-

Be it known that 1, EDWIN NoRroN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in a Combined Cork and ScrewNozzle, of which the following is a specification.

My invention relates to screw-cap nozzles for cans and like packages.These nozzles are ordinarily made of zinc, and are usually formed from asingle circular blank by spinning it up into the desired shape, thecentral portion of the blank being cut out to form the opening.

In this way a screw-nozzle is formed very cheaply; but in cans orpackages designed to contain many different articles it is also desirable or necessary to close theinozzle or openingwith a supplementalcork in order to make it tight and. prevent leakage. This heretofore hassometimes been done by placing a flat corkdisk across the top of thenozzle, which is con fined within the nozzle-cap and pressed with itsend against the top of the nozzle by the screw-cap of the nozzle, thediameter of the cork being larger than the opening in the nozzle.

The object of my invention is to provide, a combined screw and corknozzle of simple construction, and which may be cheaply manufactured bya very simple process. This I do by simply turning the central portionof the blank (which heretofore has usually been out away to form thenozzle-opening) down inside the nozzle, thus at once making or enlargingthe opening in the nozzle, and forming a cork nozzle inside thescrew-nozzle. It will be understood that a small central opening is cutout of the blank and the remainder of the central portion turned downinside the nozzle, to form the cylindrical wall for the cork to fit in.

My combined cork and screw nozzle, it will therefore be seen, is formedfrom a single piece or blank, is made in a very simple and cheap manner,and requires no more stock than an ordinary screw-nozzle, as the corknozzle is formed from that part of the blank which heretofore has beencut out to form the opening in the screw-nozzle; and my corkand screwnozzle has also other advantages incident to its tical flange at the topof the nozzle.

being composed of a single piece than the saving of labor and materialrequired in its manufacture, which will be readily understood by thoseskilled in the art to which my invention relatesas, for example, thegreater neatness, strength, and durability of the nozzle itself.

In the accompanying drawings, which form a part of this specification,Figure 1 is a sectional view of a device embodying my invention. Fig. 2is a plan view of the sheet-metal blank from which the nozzle is made.Fig. 3 is a similar view of the same after it is spun up into the formof a screw-nozzle; and Fig. 4 is a central section of the same as shownin Fig. 3, and showing also the cork nozzl'e in dotted lines.

In the drawings, A represents the blank from which the nozzle is made.It is first turned or spun up in the ordinary manner into screw-nozzleshape, as'shown in Figs. 3 and 4. A small opening, a, is cut in thecenter of the blank. This may be done either before or after the blankis formed into screw-nozzle shape.

drical wall in which a cork, 0, may be fitted.-

D is the screw-cap, provided with screwthreads (2, corresponding to thescrew-threads a on the nozzle. The annular central portion, B, whenturned down, forms an inturned ver- In turning down the interiorflange,,B, a hollow or annular mandrel is inserted inside thenozzle,

to form a support for said flange while itis' being turned or spun down.

In operation the cork is first inserted in the nozzle and then thescrew-cap applied.

I claim The combination, with a screw-cap, of a screw-nozzle providedwith an inturned vertical flange at its top, and a cork fitting withinsaid vertical flange, substantially as specified.
